The main nitronorbornene adduct derived from the asymmetric Diels-Alder reaction of (S)-benzyl-4-(3-(3-nitroacryloyloxy)-4,4- dimethyl-2-oxopyrrolidin-1-yl) benzoate (S)-1 and cyclopentadiene was isolated and transformed to afford the enantiopure bicyclic beta-amino acid (1S,2R,3R,4R)-trans-beta-norbornane amino acid 9. The enantiomer (1R,2S,3S,4S)-9 could be obtained by the same synthetic route by using the chiral auxiliary (R)-1. (c) 2007 Elsevier Ltd. All rights reserved.
